Protect your ventilator investment for up to one year.

The Puritan Bennett Re/X800 filter and drain system is designed for use with the Puritan Bennett™ 840 ventilator. It reduces particles and bacteria in a patient's exhaled gas, protecting the ventilator’s exhalation and spirometry systems.


  • Comprehensive condensate drainage system includes filter, collector vial and optional drain bag
  • Optional drain bag allows for condensation removal without breaking ventilator circuit
  • Designed to withstand up to 100 autoclave sterilization cycles at temperatures not to exceed 135 °C, 275 °F
  • Filter replacement after one year of service or 100 autoclave cycles, whichever occurs first
  • Viral and bacterial filtration efficiency of greater than 99.999%
  • Resistance to flow less than 2.5 cmH2O at 100 L/min when new
  • Minimum of 99.97% filtration efficiency of 0.3 microns normal particle size at 100 L/min flow
  • Meets CDC requirement for n100 filtration

Indications for Usage

  • To help protect caregivers and ventilator components from harmful effects of patient contamination.
